"Costing only USD 100, the Rosewill Libertas 800 W (LIB800) is a power supply that comes with a full modular cabling system, synchronous design, and DC-DC conversion for the +5 V and +3.3 V outputs. The manufacturer promises it can deliver 800 W at 50º C, peaking 900 W for up to 12 seconds. One big curiosity about this unit is that it is officially an 80 Plus Gold power supply, but Rosewill decided to downgrade it to 80 Plus Bronze."
